I've been getting headaches and was diagnosed with gingivitis recently, i don't know if it is because of my braces or something else?

Braces: Braces can immflame your gums and cause gingivitis, due to acummulatuin of plaque. Have your teeth clean on a regular bases by your dentist/hygienist. Gingivitis should not cause headaches, but...

Hygiene: you need better oral hygiene while wearing braces. As far as the headaches, that's a different issue

Headaches: Headaches would not be a direct result of either braces or gingivitis. Gingivitis most likely from inadequate oral hygiene. Headaches may be from stress, dehydration or other cause.

2 separate problems: These 2 problems should be addressed separately. 1. gingivitis, gum disease, see your dentist. 2. Headache, especially tension type headache, could be related to your orthodontic treatment, see your orthodontist for evaluation and management.
